Well, apparently I was mistaken... Sorry for any confusion.

The idea of EOF optimized @stuff always kind of made sense to me, but I have no clue anymore where I got the idea that this is actually done.

No.

The @keypath-actions are something that NSArray does. And NSArray knows nothing about EOF.

Hm, this could easily be overridden by an EOF specific subclass... An NSArray (a fault) that would respond to objectAtIndex(...) by firing the fault and returning the appropriate object, but would respond to valueForKeyPath("attribute.@sum") by asking EOF to evaluate it directly. No? Well, maybe I am pushing this idea way too far :)


Anyway, my confusion..
